Gonna try using PPA you offered.Xorg-edgers actually broke my system couple days ago, so i'm not gonna try it again.Thanks for reply!

I tryed this "x-updates" PPA, but I'm still getting this dialog and messages in the terminal :(

Same problem here. AMD HD 4890, using the legacy driver and Xorg 1.12.4 (latest supported version for legacy)

This is not valve´s fault, it's AMD being lazy, but it would be nice if you could do something about it.

Good news on that front. I've been talking with AMD and they are setting up a forum for issues encountered when using their driver with Steam for Linux. I'll announce something in the group when they go live. You can then tell them exactly what they need to focus on.

Did this PPA work? Having the same issues here. On the other hand, love the fact that it's coming for Linux and being part of the beta.
